Answer:
A) 552 inches
Step-by-step explanation:
To calculate the length of wood needed for each student's ramp, you need to multiply the length of the model ramp by the scale factor, which is 4 in this case:
6 inches (model ramp length) * 4 (scale factor) = 24 inches
Now that you know the length needed for one student, you can find the total amount for all 23 students:
24 inches (length for one student) * 23 students = 552 inches
Therefore, Ms. Steinbeck will need 552 inches of wood for all of the ramps.
